具体实施方式Detailed ways

实施例一Embodiment 1

单管塔一阶无级变频变阻尼式电涡流单摆阻尼器的无极调频调阻尼原理为将磁钢环形布置在质量块周围，这些磁钢固定在阻尼器外筒上并可以沿筒壁零活调节高度，单摆摆动幅度固定时，不同的磁钢布置位置使质量块摆动过程中到达磁钢的距离不同，从而产生不同的吸力和阻尼力，当磁钢靠下布置时，磁钢对质量块吸力增加，阻尼力也增加，从而使阻尼器频率增大，阻尼比增大；当磁钢靠上布置时，磁钢对质量块吸力减小，阻尼力也减小，从而使阻尼器频率降低，阻尼比降低。The stepless frequency modulation damping principle of the single-tube tower first-order stepless frequency variable damping eddy current pendulum damper is to arrange the magnets in an annular shape around the mass block. These magnets are fixed on the outer cylinder of the damper and can move along the cylinder wall. When the height of the pendulum is adjusted and the swing amplitude of the pendulum is fixed, different magnet arrangement positions will cause the mass block to reach the magnet at different distances during the swing process, thus producing different suction and damping forces. When the magnet is arranged downward, the magnet will affect the mass. As the suction force of the mass block increases, the damping force also increases, thereby increasing the frequency of the damper and the damping ratio. When the magnets are arranged upward, the suction force of the magnets on the mass block decreases and the damping force also decreases, thus causing the frequency of the damper to decrease. The damping ratio is reduced.

见图1至图3，本实施例的单管塔一阶无级变频变阻尼式电涡流单摆阻尼器，包括顶板1、外筒8和设于外筒内并沿所述顶板摆动的摆杆3，所述摆杆连接有质量块4，还包括与所述质量块产生阻尼效果的磁钢组件，所述磁钢组件通过调节定位组件沿外筒侧壁进行纵向调节并定位。所述磁钢组件包括磁钢固定板7和设于磁钢固定板上的磁钢5，所述外筒上设有纵向调节槽9，用于供所述调节定位组件进行纵向调节。所述磁钢固定板上的磁钢通过调节定位组件沿外筒侧壁进行纵向调节并定位。所述调节定位组件为调节螺栓6。Referring to Figures 1 to 3, the single-tube tower first-stage stepless variable frequency variable damping eddy current pendulum damper of this embodiment includes a top plate 1, an outer cylinder 8 and a pendulum located in the outer cylinder and swinging along the top plate. Rod 3, the swing rod is connected to a mass block 4, and also includes a magnetic steel assembly that produces a damping effect with the mass block. The magnetic steel assembly is longitudinally adjusted and positioned along the side wall of the outer cylinder through an adjustment and positioning assembly. The magnetic steel assembly includes a magnetic steel fixing plate 7 and a magnet 5 located on the magnetic steel fixing plate. The outer cylinder is provided with a longitudinal adjustment groove 9 for longitudinal adjustment of the adjustment and positioning assembly. The magnetic steel on the magnetic steel fixing plate is longitudinally adjusted and positioned along the side wall of the outer cylinder through the adjustment and positioning assembly. The adjustment and positioning component is an adjustment bolt 6.

如图1所示，万向节2,摆杆3，质量块4连接后悬挂在顶板1上从而组成了单摆结构。磁钢5和磁钢固定板7组成了磁钢组件，并通过调节螺栓6固定在外筒8上。As shown in Figure 1, the universal joint 2, the pendulum rod 3, and the mass block 4 are connected and suspended on the top plate 1 to form a simple pendulum structure. The magnetic steel 5 and the magnetic steel fixing plate 7 form a magnetic steel assembly and are fixed on the outer cylinder 8 through the adjusting bolt 6.

如图2所示，磁钢固定板7,磁钢5组成了磁钢组件，通过调节螺栓6固定在外筒8上，当质量块4摆动时，远离磁钢的一侧吸力减小，靠近磁钢的一侧吸力增大，且吸力增大的速度大于吸力减小的速度，因此对于质量块会收到一个沿运动方向增大的力，则质量块的频率增加。该运动过程中，金属材质的质量块受到的磁钢通过的磁通量发生变化，从而产生阻尼效果。As shown in Figure 2, the magnetic steel fixing plate 7 and the magnetic steel 5 constitute the magnetic steel assembly, which is fixed on the outer cylinder 8 through the adjusting bolt 6. When the mass block 4 swings, the suction force on the side away from the magnetic steel decreases and the side closer to the magnetic steel decreases. The suction force on one side of the steel increases, and the speed at which the suction force increases is greater than the speed at which the suction force decreases. Therefore, the mass block will receive a force that increases along the direction of movement, and the frequency of the mass block increases. During this movement, the magnetic flux passed by the magnetic steel changes when the metal mass block is affected, thereby producing a damping effect.

如图3所示，磁钢组件通过调节螺栓6固定在外筒8上，并且磁钢组件的高度位置可以沿外筒的外筒纵向调节槽滑动，并通过调节螺栓拧紧固定。As shown in Figure 3, the magnetic steel assembly is fixed on the outer cylinder 8 by adjusting bolts 6, and the height position of the magnetic steel assembly can slide along the longitudinal adjustment groove of the outer cylinder, and is tightened and fixed by adjusting bolts.

磁钢组件的高度调节示意如图1所示，H1为调节位置示意。The height adjustment diagram of the magnetic steel component is shown in Figure 1, and H1 is the adjustment position diagram.

所述磁钢至少为一个，环状位于质量块四周。所述磁钢固定板依数个磁钢环状成型设置。所述磁钢固定板上设有数个定位孔，用于供调节螺栓的插入拧紧定位。所述质量块设为圆柱形。所述顶板通过万向节2与质量块连接。所述质量块沿外筒轴向设置，质量块的轴向长度大于/等于所述纵向调节槽的纵向长度。方便纵向调节适当高度。There is at least one magnetic steel, which is located annularly around the mass block. The magnetic steel fixing plate is arranged in the shape of several magnetic steel rings. The magnetic steel fixing plate is provided with several positioning holes for inserting and tightening positioning of adjusting bolts. The mass block is set to be cylindrical. The top plate is connected to the mass block through a universal joint 2. The mass block is arranged along the axial direction of the outer cylinder, and the axial length of the mass block is greater than/equal to the longitudinal length of the longitudinal adjustment groove. Convenient to adjust the appropriate height vertically.

当摆杆摆动角度相同时，磁钢组件处于下端位置时的阻尼大于磁钢组件处于上端位置时的阻尼。When the swing angle of the swing bar is the same, the damping when the magnetic steel assembly is at the lower end position is greater than the damping when the magnetic steel assembly is at the upper end position.

具体实施时，当摆杆摆动角度相同时，磁钢组件的调节位置越靠下，则质量块越靠近磁钢组件，此时质量块收到的吸力越大，则频率越高，阻尼越大，磁钢组件的调节位置越靠上，则质量块越远离磁钢组件，则频率越低，阻尼越小，磁钢位置调节沿槽位置固定，因此频率调节和阻尼调节均为无级调节。In specific implementation, when the swing angle of the pendulum is the same, the lower the adjustment position of the magnetic steel assembly is, the closer the mass block is to the magnetic steel assembly. At this time, the greater the suction force received by the mass block, the higher the frequency, and the greater the damping. , the higher the adjustment position of the magnetic steel component is, the further the mass block is away from the magnetic steel component, the lower the frequency and the smaller the damping. The magnetic steel position adjustment is fixed along the slot, so the frequency adjustment and damping adjustment are both stepless adjustments.

以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above-mentioned specific embodiments further describe the purpose, technical solutions and beneficial effects of the present invention in detail.
